Detaljert beskrivelse
This is an observational, retrospective cohort study on the treatment utilization and outcomes of Macrophage Activation Syndrome (MAS) refractory to glucocorticoids (GC) in patients with Still's disease. The study will be conducted entirely through medical chart abstraction; all data will be taken from the patient's medical record, with no additional assessments.
